Idaho prison officials say 364 inmates exploited a software vulnerability in the JPay tablets they use for email, music, and games to collectively transfer nearly a quarter million dollars into their accounts.

In a prepared statement, Idaho Department of Correction spokesman Jeff Ray stated, “This conduct was intentional, not accidental. It required a knowledge of the JPay system and multiple actions by every inmate who exploited the system’s vulnerability to improperly credit their account.”

The Idaho DOC issued disciplinary reports to all those they believe to be involved. A week later, the Colorado Department of Corrections confiscates all 15,000 of its tablets claiming a “security issue.”
